What is the maximum vertical distance between the line y = x + 56 and the parabola y = x2 for −7 ≤ x ≤ 8?
atroni [7]
-7 and 8 are the solutions to the given equation system.
Therefore, the maximum distance between the y values of the two equations must lie exactly between their points of intersection. That is on x value:
x = (-7 + 8)/2 = 0.5
The maximum distance is:
y = 0.5 + 56 = 56.5
y = 0.5² = 0.25
56.5 - 0.25 = 56.25 units

The perimeter of a rectangular painting is 304 centimeters. If the length of the painting is 95 centimeters, what is its width?
alexdok [17]
Perimeter = 304cm (2xlength + 2xwidth)
length = 95cm
total length of painting = 95x2 = 190cm
total width of painting = 304-190 = 114cm
width = 114 divided by 2 = 57cm

In Exercise, expand the logarithmic expression.<br> ln x(x + 1)
34kurt

Answer:

dy/dx = 2x+1/x(x+1)

Step-by-step explanation:

y = In x(x+1)

Let u = x(x+1) = x^2 + x

du/dx = 2x + 1

y = In u

dy/du = 1/u

dy/dx = dy/du × du/dx = 1/u × 2x+1 = 2x+1/u = 2x+1/x(x+1)
